The area under a curve can be estimated by breaking the x axis into increments, evaluating the function at a point inside that increment, and approximating the area under the curve in that increment as a
rectangle. The figure below shows this approximation with an increment of 1 and the function being evaluated at the midpoint of the increment.

Write the code that will calculate the area under the curve:
y = 8 sin (x) + 0.5x² – x
(where x is in radians)
using decreasing increments until the area value converges (the difference between the area from two consecutive runs is less than 0.01%). Use the midpoint approximation method and start with an increment
of 1. Decrease the increment by half every iteration.
